Cloud Computing as a Utility The Citadel Sigma Xi
Topics What is cloud computing? A peek at origins Current and potential uses Some issues A future look
Cloud Computing You don’t know where You don’t care where You just expect a result Reasonable delay is OK How is CC like water?
Other Utilities It’s there when you need it. You don’t think about it much. Can’t/don’t want to live without it.
Computing without it… Is like living in
Origins Eniac Numerical Computer 1946 Contained 17,468 vacuum tubes,vacuum tubes 7,200 crystal diodes,diodes 1,500 relays,relays 70,000 resistors,resistors 10,000 capacitors andcapacitors about 5 million hand-soldered joints.soldered It weighed over 30 short tons (27 t),short tons was roughly 8 by 3 by 100 feet took up 1800 square feet and consumed 150 kW of power.kW Shutdown in (Wikipedia, “ENIAC”)
Cousins Mainframe Built to run reliably for decades Transaction processing Modern virtualized servers are mainframe computers IBM Mainframe circa 1964 IBM z9 circa 2005
Cousins Titan Supercomputer 200 cabinets 4,352 square feet Draws 480 V/cabinet Peak 8.2MW power Total 299,008 processor cores, Total TiB of CPU and GPU RAM Blazing fast interconnect Hearing protection required in server room (fan noise) Wikipedia, “Titan_(supercomputer) Titan circa 2011
Economics of (Super) Computing -Kathy Yellick, NERSC, 2010
Want to See a Magic Trick?
Another flavor, called “MapReduce” made famous A Rabbit…Really?! really_big_data_list x,y; for i is 1 to n do y[i] = f(x[i]); end; really_big_data_list x,y; y = map(f, x);
Social Issues Aggregation of Information Abuse of trust Security (Information) Privacy Intellectual Property Control Freedom to choose
Energy Issues In 2011, and average Google search used 0.3 watt-hrs of electricity Google data centers use 260 MW (2011) worldwide annually – enough to power 200,000 homes in Richmond, VA or Irvine, CA – Only 2kWh per person
Our Own “Doodoo” Problem We create 2.5 exabytes (10 18 ) of data every day We can’t process it fast enough We can’t move it fast enough Digitally, we are drowning in data we cannot use.
My vision for Cloud Computing… High-fidelity results
